Contactless Physiological Monitoring (VCPM) refers to the use of advanced imaging and computer vision technologies to monitor physiological parameters (e.g., heart rate, respiratory rate, blood oxygen levels, etc.) without requiring direct contact with the subject. This technology leverages non-invasive methods like cameras and advanced algorithms to extract vital signs from visual data, making it ideal for healthcare, security, and wellness applications.
How It Works
- Imaging Devices: High-resolution cameras (RGB, infrared, or thermal) capture visual information about the subject.
- Signal Extraction:
- Remote Photoplethysmography (rPPG): Detects subtle color changes in the skin caused by blood flow.
- Thermal Imaging: Measures heat patterns to determine respiratory rate and other metrics.
- Motion Analysis: Tracks movements associated with breathing or other physiological activities.
- Processing and Analysis: Machine learning and AI algorithms analyze the captured data to extract and interpret physiological signals.
- Output and Integration: Results are presented in real-time and can integrate into broader healthcare or monitoring systems.
Visual Contactless Physiological Monitoring (VCPM) is an emerging technology that can measure the vital signs based on videos. It has been proven that VCPM is highly effective in monitoring blood volume pulse (BVP) signal, heart rate (HR), respiratory rate (RR), oxygen saturation (SpO2), and blood pressure (BP).
More significantly, VCPM’s contactless characteristic offers clinical benefits such as user-friendliness, full automation, long-term monitoring, zero skin damage, improved clinical workflow efficiency and the greatly reduced risk of cross-infection. Particularly, VCPM can also play a critical role in combating cardiovascular diseases (CVDs) and offer full-cycle personal health management
